How to learn vertex number in Revit?

[alicik793]

Hello everybody. I am an architect and i build a metaverse world. We use unity and i export my project to unity. I need learn vertex number in revit. Is there any option about showing vertex number about entire project? Thank you very much.

I am not aware of any such thing in Revit or its API. In Revit, the BIM elements can be identified by their element id or unique id, cf.:

The only way I can think of to identify an individual vertex is to query it for its reference and query that for its stable representation:

I hope this helps. Please let us know whether and how you solve your task.

If you want vertices, you could tessellate the geometry. But I think you want to make a custom exporter.
